SHINGLEI-EDGING MACHINE.

SPECIFICATION forming part of Letters Patent at; 302,121, dated July 15', 1884. Application filed May 3, 1884. (No model.) 7

To all whom it may concern Be it known that I, JOHN A. FRENZEL, of WVausau, in the county of Marathon, and in the State of Wisconsin, have invented certain new and useful Improvements in Shingle-Edging Saws; and I do hereby declare that the follow-- ing is a full, clear, and exact description thereof.

My invention relates to improvements in shingle edging or jointing machines; and it consists of certain peculiarities of construction, as will be fully described hereinafter.

In the drawings, Figure 1 is aside elevation of my improved device. Fig. 2is alike view showing the opposite side of themachine,partly in section on the line a: :v'of Fig. 3. Fig. 3is a top View of the machine, and Fig. 4 is a rear end View of the machine.

A A indicate the frame of my machine. 13 B is the edgingsaw mounted, as usual, on the shaft 1), running in the box-bearings of the frame. The shingle-table 0 runs, as in ordinary machines, on rails c 0, supported on ad- 3' ustable brackets G O, in the ordinary manner,

the improvement I have designed consistingmerely in the arm D and its connections, the purpose of which is to hold the shingle in place when presented to the saw, the teeth of which are shaped so as to cut from the under side of the shingle. This arm D is hinged in any suitable manner, as by shaft D journaled in the upper ends of the brackets 61 d, bolted to- It is y connected by the screw-bolt d the arm itself being adapted to receive an adjustment on said bolt by means of the slot (2 A similar slot, (1, formed in about the center of thearni D, serves to adjust in its attachment on bolt d the leg E, which supports the arm in position for use. The lower end of the leg E is notched on its rear edge, and the shoulder 6, so formed, rests against the upper face of the plate E, bolted to the frame. .In the front edge of this plate an open slot, 0, (shown in dotted lines in Fig. 3,) is cut to receivethe inner edge of the notched end of the leg E, which is thus guided in its up and down m0- shingle as it is carried under it by table 0; Y

- and as the table 0, on which the shingle to be trimmed'is carried, advances, the shingle is wedged tightly between the point f of the eccentric F and the top of table 0, and is held p by the weight of the arm D againstthe under cutting action of the saw; but after the out has been made, and as soon as the return of the table begins, the eccentric will be lifted, and the weight of the arm D will be taken by the plate E, so that there will be no resistance to the withdrawal of the shingle. To allow of the adjustment of the pressure which the point .f of the eccentric F exerts against the shingle, I provide a weight, G, the perforated shank g of which is adapted to rest in either one of the notches g g, formed in the upper edge of the horizontal bar G, fastened in any suitable manner on the outer face of the arm D, as shown at g H is a flanged plate, which I propose to attach by a slot'and an adjustable bolt, h, to the front end of the arm 011 the outer face of the same. This plate will serve as a guard or guide to prevent the waste from too much of the shingle being presented to the saw.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In ashingle-edging machine, the combi nation, with a traveling table, of a hinged arm, D, and eccentric F, pivoted thereto, and the saw, substantially as described.

-2. The combination 'of the saw, hinged arm, and eccentric pivoted thereto, with theshingle-table-supporting leg and its plate E, substantially as described.

3. The hinged arm D, its adjustable weighting mechanism, and pivoted eccentric and supporting-leg E, all combined with the traveling table," saw, and plate E", as set forth.

4. The combination of the saw and traveling table, hinged arm, and eccentric pivoted thereto, with the supporting-leg adj ustably secured thereto, and its supporting-plate, the latter adjustably secured totheirameofthemachine, In testimony that I claim the foregoing I substantially as described. have hereunto set my hand, at Milwaukee, in 10 5.
